Heater covers more than the furnace: mini-splits, baseboard heaters, space heaters, and heat pumps all warm New York homes. This page explains the faults each one shows and how they are fixed.

When a caller says the heater is not working, the unit in question may be a furnace, a mini-split, a baseboard heater, or a space heater, and each one fails differently. 'My heater's not working.' 'Hi, my heater's not working.' 'Yeah, just calling about heating repair.' The first job of the visit is to learn which heater the home has and what it is doing, because the fix follows the unit.

This page covers the heaters beyond the furnace: mini-splits that blow cool air instead of heat, baseboard heaters with bent fins, space heaters that will not start, and heat pumps that stop carrying the load. Furnace faults have their own pages; this one is for the rest of the heat in the home, and for the homes where two kinds of heater work together.

Heaters That Won't Turn On

'my heater will not work like it will turn on at all.' That report arrives for furnaces, mini-splits, and space heaters alike, and the check starts the same way: power, thermostat or controls, and the unit itself.

'It just won't turn on.' 'Right now it's not turning on.' 'No, nothing's clicking on.' When nothing at all responds, the thermostat or the control board is often the fault. 'The thermostat turns on, but the unit's not working' is the report when the controls look alive and the heater stays dead, and the wiring between the two is tested before the heater is opened.

A heater that turns on and shuts off is a different fault. The pattern is a safety switch, an overheating sensor, or a control that cannot hold the call for heat. The technician watches the unit through a full cycle to see where it stops, then tests the part that should have acted.

Mini-Split Heating Problems

Mini-splits heat and cool the same room, and their heating faults are easy to miss in summer. 'It's two mini splits that are only blowing cool air, not heat.' The units run, the fans move air, but the air never warms.

'I have a mini-split that hasn't been heating or cooling in a while' is the report when the unit has been failing quietly for months. A mini-split that heats weakly may be low on refrigerant, its filters may be clogged, or its outdoor coil may be iced or dirty. The filters are cleaned, the coil is checked, and the refrigerant is tested before any part is blamed.

Mini-split service is part of heating maintenance in New York homes that rely on them. 'I need service for a mini split.' 'I would just like somebody to come and inspect and potentially clean a mini split.' Cleaning covers the filters, the indoor coil, and the drain, and the visit ends with the unit run in heat mode through a full cycle.

Baseboard Heaters and Space Heaters

Baseboard heaters are simple units, and their faults are simple too: bent fins, dust packed between the fins, or a thermostat that no longer calls for heat. 'I'm calling to see if you guys do clean the baseboard heater fins' is a call we hear when the fins are bent or clogged and the room stays cold.

Electric baseboard heaters are checked at the thermostat, the wiring, and the element. A heater that stays cold may have a failed thermostat or a burned element, and a heater that stays hot may have a thermostat that will not open.

Space heaters are a different case. A space heater that will not start, or one that shuts off after a few minutes, usually has a safety switch or a tip-over sensor at fault, or a heating element that has failed. Space heaters are checked for safe operation as well as for heat, because a space heater that runs hot on a damaged cord is a fire risk, and it is not put back into service.

Heat Pumps and Whole-Home Heating

Heat pumps heat by moving heat from outside air into the home, and they work well until the cold deepens. 'I have an upstairs heat pump that doesn't seem to be working' is the call when the pump stops carrying the load.

'I would like somebody to take a look at my heat pump because it's not working right.' A heat pump that runs but does not heat may be low on refrigerant, its outdoor coil may be iced, or its reversing valve may not switch to heat mode.

Whole-home heating often mixes systems: a furnace downstairs, a mini-split in the addition, baseboard heat in a cold room. When one part of that mix fails, the home heats unevenly, and the fix is to find which unit has stopped carrying its share.

A heater repair visit ends the same way a furnace visit does: the unit is run through a full heating cycle while the technician watches. The heater starts, warms the air, reaches the thermostat setting, and shuts down as it should.

Frequently Asked Questions

Why is my mini-split blowing cool air instead of heat?

The unit may be left in cool mode, or it may be low on refrigerant with a dirty outdoor coil. The mode is checked first, then the filters, the coil, and the refrigerant. A mini-split that heats weakly is often a cleaning or refrigerant fault, not a dead unit.

My baseboard heater stays cold in one room. What causes that?

A failed thermostat, a burned element, or fins bent and clogged with dust. Each baseboard heater is tested on its own, because one failed unit leaves one cold room. Cleaning and straightening the fins restores airflow, and a failed thermostat or element is replaced.

Why does my heater turn on and then shut off?

A safety switch, an overheating sensor, or a control that cannot hold the call for heat. The technician watches the unit through a full cycle to see where it stops, then tests the part that should have acted at that point.

Do you service heat pumps as well as furnaces?

Yes. Heat pumps are checked at the outdoor coil, the refrigerant, and the reversing valve, and dual-fuel handoffs to the furnace are tested. A heat pump that runs but does not heat is often a coil or refrigerant fault.

My space heater keeps shutting off. Is it safe to keep using?

No. A space heater that shuts off may have a safety switch or tip-over sensor at fault, or a damaged cord. It should be checked before it is used again, and a heater with a damaged cord is not put back into service.
